I think you are rusty. Usually when I lay off tennis for a few weeks, I get a few aches at the start of my hitting sessions cuz of hitting off centre. But once I'm grooved in and hitting the ball nicely in the middle of the racquet, I don't notice the shocks anymore even if i forgot to restring and am using very very dead polyester.
Dead poly definitely feels harsher than freshly string poly but I find the difference not as significant as when I'm really misfiring.
